The district policy is that those not “up to date” ( 2 shots and a two week old booster) who are exposed must stay home 5 days after contact and test negative before returning.
Those up to date who have had Covid in the last 3 months can just continue working. Those up to date who have not recently had Covid just test. They can work as soon as they have a negative test.
I know it is full of holes, but that’s the policy.
